- ItemThe effectiveness of bioregional planning as a tool in protecting threatened species in South Africa(2017-06-22) Daya, Sarisha; De Crom, EngelaSouth African biodiversity is threatened by different pressures, ranging from habitat loss and degradation to harvesting and intrinsic factors. There currently are protection measures to conserve our species, ranging from formally protected areas to biodiversity stewardship programmes with land owners. Although taking into account a wide variety of threats, species risk of extinction assessments, as well as protection initiatives, do not cater for the effect of climate change on species distributions and persistence at a national scale in South Africa. Using distribution data for bats, birds, butterflies, reptiles and spiders; areas of high animal diversity and endemism (AHDE) were identified. The current and future geographic patterns were projected using a species distribution model in MaxEnt. A total of 19 bioclimatic variables including altitude, geology and soils were used in predicting geographic distribution models. The computed suitable current climatic conditions are similar to the species occurrence records, suggesting that the tested variables are appropriate to predict biogeographic range. Climate change modelling projections for 2080 indicate a decline in the bat, bird, butterfly and spider distributions, and an increase in the reptile distributions across the country. These shifts culminated to the shift in our AHDE, moving them out of the boundaries of the current protection initiatives/measures. Our results suggest that future protected area expansion strategies should take into account the effect of climate change on species ranges, and cater for the potential shifts.
